Patented Oct. 15, 1929 UNITED STATES PAUL AMBORY, 0F HAZEL PARK, MICHIGAN ELECTRIC WATER HEATER Application led November 12, 1928. Serial No. 318,741.

My invention relates to a new and useful improvement in an elect-ric water heater and has for its object the provision of device of this class which will be simple in structure,

5 economical of manufacture and highly eiiicient in use.

Another object of the invention is the provision in an electric water heater oi this class, of a sectional casing engaging an insulating 3g heating element supporting member.

Another object oi' the invention is the provision of an electric Water heater having an insulating heating element suppor meniber provided with flanges for en I' gir and retaining in position 'the sections of an inclosing housing.

Other objects will appear hereinafter.

The invention consists in the combination and arrangement of parts hereinafter tcfj/i scribed and claimed.

The invention will be best understood fro a reference to the accompanying drawiigs which form a part of this speciiication au@ in which,

i.; Fig. 1 is a perspective view of the invention.

Fig. 2 is a sectional view taken on line 2---2 of Fig. 3.

Fig. 3 is a s ctional view taken on line 3-3 y Of Fig". 2.

Fig. 4 is a fragmentary perspective view of an insulating member used in the invention.

The device comprises a housing formed g5 from a pair of sections 7 and 8, each ot which is provided with a plurality of slots 9 and 10. For heating purposes a heating element 11 in the nature of a resistance coil is projected through an eyelet 12 formed on the re- 3 inforcing portion 13 oi the insulating ring 11i, which is formed T-shaped in close section as shown in Fig. 4, to provide the downwardly projecting flange 15 and the upwardly projecting flange 16. A recess 17 is formed in J.: this insulating material to accommodate a cable 18 in which are carried the wires 19 and 20, which are attached to the opposite ends ot the heating coil 11, this heating coil being projected through the veyelets 21 and 22 formed on the insulating ring 14. An axially extending groove 23 is formed in the iiange 16 and likewise in the flange 15, this groove communicating with a circumierentially e2:- tending groove 24 to provide a bayonet slot for the reception of the boss 25 which projects outwardly from the periphery of the housing sections 7 and 8.

In assembly these sections are engaged with the inner surface of the flanges 1G and 17, the boss engaging in the bayonet slot and serving to bind these sections on the ring. In the form shown 3 ot these bayonet slots are provided although the number may be optional.

An electric water heater constructed in this manner is one which is light, durable, easily and quickly assembled and one which provides ample protection for the heating element.

While I have illustrated and described the prefered form of my invention I do not .vish to limit myself to the precise details or" structure shown but desire to avail inyselic of such variations and modifications as come witl in the scope of the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. An electric water heater of the class described comprising: an insulating meinteL g a heating coil supported by said insulating member; and a housing, comprising a pair oi sections, mounted on said insulating member and inclosing said coil; and flanges on said insulating member engaging the periphery of each of said housing sections.

2. An electric water h ater oi' the class described comprising: an insulating' meiniiicr; a heating coil supported by said insulating member; and a housing, comprising a pair of sections, mounted on said insulati ber and inclosing said coil, said Hang; i having bayonet slots formed therein; and av boss on the periphery of each of said housing sections for engaging in said bayonet slots.

In testimony whereof I have signed the foregoing specification.

PAUL AMBOPY.
